Deep Earth carbon reactions through time and space
2020
Reactions involving carbon in the deep Earth have limited manifestations on Earth’s surface, yet
they have played a critical role in the evolution of our planet. The metal-silicate partitioning reaction
promoted carbon capture during Earth’s accretion and may have sequestered substantial carbon in
Earth’s core. The freezing reaction involving iron-carbon liquid could have contributed to the growth
of Earth’s inner core and the geodynamo. The redox melting/freezing reaction largely controls the
movement of carbon in the modern mantle, and reactions between carbonates and silicates in the deep
mantle also promote carbon mobility. The 10-year activity of the Deep Carbon Observatory has made
important contributions to our knowledge of how these reactions are involved in the cycling of carbon
throughout our planet, both past and present, and has helped to identify gaps in our understanding that
motivate and give direction to future studies.
